What wire on Vehicle do you have TACH wire hooked to

& Door UNLock wires???

Due To Accessory Power Loss At Generic Electronic Module,Power Door Locks Will Become Inoperable 2 Minutes After Last Door Is Locked And Closed. To wake up the G.E.M Send A Negative Pulse To The BLACK / YELLOW Driver Door Pin Wire With the Unlock Pulse. Diode Isolate, Cathode (Band Side) Of Diode Faces Away From Vehicle Wires.

tach is hooked up to the black / green wire at the ignition coil.

door ulock is to the white black wire in driver kick panel

With the newer dei stuff the only reliable way to get a tach signal on the fords is use a fuel injector wire.

ok so for now i turned the tach mode off and its just running the starter for the default .6 sec and it seems to be working.

as for the door lock and unlock i'm getting kinda sketchy results from them

when i arm the alarm and all doors are unlocked they will all lock. if i arm the alarm and only one door is unlocked (ie: the driver door unlocks when i open it) it wont lock any doors. if i disarm the alarm ONLY the passenger door unlocks.

I'm not shure what the diode isolation would do but i will try it i guess MO12V if you could draw that out for me or explain how to hook that up a little more in detail that would be great.

black orange

black yellow

are they still 5 wire systems or do i just tap into them with the default (-) (+) from the brain?

Use a 1N4001 Diode or similar.......

Diode has a CATHODE ( Band on Diode ) and an ANODE side.

This allows ( basically ) a ONE WAY Current. This will prevent "feedback" from whatever you are hooking up

See: https://www.the12volt.com/diodes/diodes.asp for better explanation

Door Locks are NEGATIVE Pulse...........

In other words..........From your UNLOCK wire of your 791, hook a wire & Diode ( facing the Cathode side toward 791 ) to the Driver Door PIN to wake up the G.E.M. after the doors have been locked for over 2 minutes
